The best way to do this, therefore, is to create a virtual world with images captured by cameras. For interactive response, which is essential for VR, the system needs to change the image being displayed according to where the human operator, whom we call as a virtual viewing point, is viewing from. In other words the system has to deal with the occlusion problem, which is mainly caused by motion parallax. This paper proposed a solution to the occlusion problem. It introduces scenery planes which sample the real world as flat planes based on the assumption that these planes are sufficient to represent the world while the virtual viewing point is moving. There are two types of scenery planes: far planes, which do not need to consider depth during movement, and near planes, which do need to consider depth. The method is verified by a prototype system with stereoscopic viewing ability.","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"244","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ozaki, Nobuyuki"}]},{"nameIdentifiers":[{"nameIdentifier":"245","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tachi, Susumu"}]}]},"item_2_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本バーチャルリアリティ学会"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11429722","subitem_source_identifier_type":"NCID"}]},"item_2_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"007","subitem_subject_scheme":"NDC"},{"subitem_subject":"548","subitem_subject_scheme":"NDC"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学先端科学技術センター"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"尾崎, 信之"}],"nameIdentifiers":[{"nameIdentifier":"242","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"舘, 暲"}],"nameIdentifiers":[{"nameIdentifier":"243","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-30"}],"displaytype":"detail","filename":"tachi_1997_042c.pdf","filesize":[{"value":"634.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tachi_1997_042c.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/63/files/tachi_1997_042c.pdf"},"version_id":"0dc379de-dddf-4bfe-a96f-5a08b0097bf9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Tele-existence","subitem_subject_scheme":"Other"},{"subitem_subject":"Virtual Reality","subitem_subject_scheme":"Other"},{"subitem_subject":"Virtual World","subitem_subject_scheme":"Other"},{"subitem_subject":"Motion Parallax","subitem_subject_scheme":"Other"},{"subitem_subject":"Occlusion","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"自然風景を仮想空間内で再生するシステムの開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"自然風景を仮想空間内で再生するシステムの開発"}]},"item_type_id":"2","owner":"1","path":["31","14"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-06-06"},"publish_date":"2007-06-06","publish_status":"0","recid":"63","relation_version_is_last":true,"title":["自然風景を仮想空間内で再生するシステムの開発"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:41:00.860673+00:00"}
